Synthesis and characterization of symmetric cyclooctatetraindoles: Exploring the potential as electron-rich skeletons with extended π-systems

A facile one-pot tetramerization of indolin-2-one with phosphoryl chloride was applied for the first convenient direct synthesis of C2v- symmetric cyclooctatetraindole with an 8π annulene as the center. Tetra- and octa-arylated cyclooctatetraindole derivatives functionalized with fluorescent fluorene and pyrene units were thus facilely synthesized and characterized.

Tetra-indole core as a dual agent: A hole selective layer that passivates defects in perovskite solar cells

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.

Octupolar (C3 and S4) Symmetric Cyclized Indole Derivatives: Syntheses, Structures, and NLO Properties

Several cyclized indole derivatives have been synthesized, and their structures been determined. The C3-symmetric single-chiral N-phenyltriindole (Tr-Ph3) crystallized in the P1 space group, and the S4-symmetric saddle-like tetraindo
