Improving photovoltaic properties of the linear A-Ar-A type small molecules with rhodanine by extending arylene core

In order to efficiently tune photovoltaic performance, a series of linear A-Ar-A type small molecules (SMs) of (DRCN3T)2Ar were designed and synthesized, which contain the same terminal of 2-(1,1-dicyanomethylene) rhodanine (DRCN) and π-bridged space of 5-vinyl-trithiophene (3T), but different central arylene (Ar) unit, respectively. Significantly extending film absorption and increasing hole mobility were obtained in these SMs with enlarging Ar units from phenylene (Ph), naphthylene (Nap) to anthrylene (Ant). As a result, photovoltaic properties were remarkably improved in these SM/PC71BM based solution-processing organic solar cells (OSCs) by enlarging Ar units in (DRCN3T)2Ar. The highest power conversion efficiency of 5.15% with a short-circuit current density of 11.34 mA cm?2 was obtained in the (DRCN3T)2Ant based device, which is three times of that in the (DRCN3T)2Ph-based device. Our work further indicates that properly extending Ar core could be beneficial to improve photovoltaic properties for the A-Ar-A type SMs.

Acceptor-donor-acceptor small molecules containing benzo [1,2-b:4,5-b′]dithiophene and rhodanine units for solution processed organic solar cells

Two novel solution-processed acceptor-donor-acceptor (A-D-A) structured organic molecules with 5,8-disubstituted benzo[1,2-b:4,5-b′]dithiophene (BDT or BDTT) as central and donor units, 2-(1,1-dicyanomethylene)rhodanine (DCRD) as acceptor unit and terminal group, and trithiophene (T3) as π-bridges, D(T3-DCRD)-BDT and D(T3-DCRD)-BDTT, are designed and synthesized for the application as donor materials in organic solar cells (OSCs). Both compounds exhibit broad absorption covering the wavelength range 300-750 nm and the relatively lower HOMO energy levels from -5.39 to -5.46 eV. D(T3-DCRD)-BDTT demonstrates strong absorbance and higher hole mobility than that of D(T3-DCRD)-BDT. The power conversion efficiency (PCE) values of the OSCs based on the compounds/PC61BM (1:1, w/w) are 1.10% for D(T3-DCRD)-BDT and 1.94% for D(T3-DCRD)-BDTT, under the illumination of AM. 1.5G, 100 mW/cm-2. Furthermore, the high open-circuit voltage (Voc) values are 0.93 V for D(T3-DCRD)-BDT and 0.96 V for D(T3-DCRD)-BDTT, respectively. It indicates that incorporating DCRD as an acceptor unit into D-A-D-type small molecule has proven to be promising candidates for high efficiency solution processed OSCs.

Chirality inversion in hydrogen-bonded rhodanine-oligothiophene derivatives by solvent and temperature

The self-assembly process of hydrogen-bonded quinquethiophene-rhodanine derivatives has been explored as a function of solvent and temperature. We demonstrate the divergent supramolecular chirality emerging from a single enantiomer by subtle changes in solvent mixtures and sample preparation protocol. Spectroscopic techniques have proved the presence of aggregates where H-bonding interactions play a crucial role.

Design, synthesis and photophysical properties of A-D-A-D-A small molecules for photovoltaic application

A series of linear-conjugated small molecule compounds featured with the acceptor-donor-acceptor-donor-acceptor (A-D-A-D-A) structure were designed, synthesized and characterized. The films of the compounds showed a broad UV-Vis absorption range of 300-800 nm with high molar absorption coefficient of more than 1.0 × 104 cm-1. Their hole-mobility can be as high as 1.0 × 10-3 cm2 V-1 s-1. The compounds have a compatible HOMO energy level of -5.0 eV to PC71BM and a high solubility up to 20 mg mL-1 in chloroform. Therefore, compounds can blend with PC71BM in the chloroform and form an active layer for a photovoltaic cell device by spin-coating of the blend solution. A maximum power conversion efficiency of 3.2% was achieved with the DERH3TT solar cell device. These results indicate that the A-D-A-D-A small molecules with electron-withdrawing dyes as terminals are promising candidates for the high efficiency solution processed organic photovoltaic cells.
