We investigated the ability of a novel triazatruxene–rhodamine-based (TAT-ROD) chemosensor to detect the trivalent metal ions aluminium (Al3+), iron (Fe3+) and chromium (Cr3+). Operating via the through-bond energy transfer (TBET) pathway, the chemosensor exhibited low detection limits of 23.0, 25.0 and 170.0 nM for Al3+, Fe3+ and Cr3+, respectively, along with high sensitivity and selectivity during a brief period (15 s). The binding ratio of the chemosensor and trivalent metal ions achieved by Job’s method was 3:1, and when we added ethylenediaminetetraacetic acid (EDTA), the sensing process reversed. Altogether, our TAT-ROD chemosensor marks the first triazatruxene-based colorimetric and fluorometric metal ion sensor reported in the literature.

An organic small molecule composed of a tetra-indole core was designed and introduced as a hole selective layer for the fabrication of perovskite solar cells (PSCs). 5,10,15,20-Tetrahydrotriindole[2′,3′:4:2′,3′:5,6:2′,3′:7,8]cycloocta[1,2-b]indole (TTI) when integrated in PSCs, also passivated the defects in perovskite by suppressing the non-radiative recombination as noted from photoluminescence and electrochemical impedance (EIS) measurements and gave improved photovoltaic performances. The device showed a power conversion efficiency of 15.83% when employed as an hole selective layer, however on passivating the interface of perovskite/hole selective layer, the PCE improved significantly to 19.23%. Additionally, the TTI treated device showed improved charge transfer behaviour and long-term stability when stored in the dark under an ambient atmosphere.

Three novel donor–π-bridge–donor (D-π-D) hole-transporting materials (HTMs) featuring triazatruxene electron-donating units bridged by different 3,4-ethylenedioxythiophene (EDOT) π-conjugated linkers have been synthesized, characterized, and implemented in mesoporous perovskite solar cells (PSCs). The optoelectronic properties of the new dumbbell-shaped derivatives (DTTXs) are highly influenced by the chemical structure of the EDOT-based linker. Red-shifted absorption and emission and a stronger donor ability were observed in passing from DTTX-1 to DTTX-2 due to the extended π-conjugation. DTTX-3 featured an intramolecular charge transfer between the external triazatruxene units and the azomethine–EDOT central scaffold, resulting in a more pronounced redshift. The three new derivatives have been tested in combination with the state-of-the-art triple-cation perovskite [(FAPbI3)0.87(MAPbBr3)0.13]0.92[CsPbI3]0.08 in standard mesoporous PSCs. Remarkable power conversion efficiencies of 17.48 percent and 18.30 percent were measured for DTTX-1 and DTTX-2, respectively, close to that measured for the benchmarking HTM spiro-OMeTAD (18.92 percent), under 100 mA cm?2 AM 1.5G solar illumination. PSCs with DTTX-3 reached a PCE value of 12.68 percent, which is attributed to the poorer film formation in comparison to DTTX-1 and DTTX-2. These PCE values are in perfect agreement with the conductivity and hole mobility values determined for the new compounds and spiro-OMeTAD. Steady-state photoluminescence further confirmed the potential of DTTX-1 and DTTX-2 for hole-transport applications as an alternative to spiro-OMeTAD.

Triazatruxene derivatives find many applications as lipophilic compounds, but few examples of hydrosoluble derivatives have been reported so far. In this paper, we compare different synthetic routes for the preparation of hydrophilic triazatruxene derivatives and define the most versatile pathway. The synthesized compounds are fluorescent not only in organic solvents, as reported for other lipophilic derivatives, but also in water, making them particularly suitable for biological applications.

A cation-π induced lithium-doped conjugated microporous polymer, Li+-PTAT, was constructed. It was proved that the point to face cation-π interactions between Li+ and indole can endow the resulting Li+-PTAT with high Li+ content and without agglomeration, which further leads to its encouraging hydrogen storage capacity.

Four center symmetrical star-shaped hole transporting materials (HTMs) comprising planar triazatruxene core and electron-rich methoxy-engineered side arms have been synthesized and successfully employed in (FAPbI3)0.85(MAPbBr3)0.15 perovskite solar cells. These HTMs are obtained from relatively cheap starting materials by adopting facile preparation procedure, without using expensive and complicated purification techniques. Developed compounds have suitable highest occupied molecular orbitals (HOMO) with respect to the valence band level of the perovskite, and time-resolved photoluminescence indicates that hole injection from the valence band of perovskite into the HOMO of triazatruxene-based HTMs is relatively more efficient as compared to that of well-studied spiro-OMeTAD. Remarkable power conversion efficiency over 18% was achieved using 5,10,15-trihexyl-3,8,13-tris(4-methoxyphenyl)-10,15-dihydro-5H-diindolo[3,2-a:3′,2′-c]carbazole (KR131) with compositive perovskite absorber. This result demonstrates triazatruxene-based compounds as a new class of HTM for the fabrication of highly efficient perovskite solar cells.

A cross-linkable triazatruxene that leads to insoluble films upon thermal annealing at temperatures compatible with flexible substrates is presented. The films were used as the hole transporting and electron blocking layer in partially solution processed phosphorescent organic light-emitting diodes, reaching power conversion efficiencies of 24 lm W?1, an almost 50% improvement compared to the same OLEDs without the cross-linkable hole transporting layer.
