英文摘要	A fused-ring electron acceptor IDT-2BR1 based on indacenodithiophene core with hexyl side-chains flanked by benzothiadiazole rhodanine was designed and synthesized. In comparison with its counterpart with hexylphenyl side-chains (IDT-2BR), IDT-2BR1 exhibits higher highest occupied molecular orbital (HOMO) energy but similar lowest unoccupied molecular orbital (LUMO) energy (IDT-2BR1: HOMO=-5.37 eV, LUMO=-3.67 eV; IDT-2BR: HOMO=-5.52 eV, LUMO=-3.69 eV), red-shifted absorption and narrower bandgap. IDT-2BR1 has higher electron mobility (2.2x10(-3) cm(2) V-1 s(-1)) than IDT-2BR (3.4x10(-4) cm(2) V-1 s(-1)) due to the reduced steric hindrance and ordered molecular packing. Fullerene-free organic solar cells based on PTB7-Th:IDT-2BR1 yield power conversion efficiencies up to 8.7%, higher than that of PTB7-Th:IDT-2BR (7.7%), with a high open circuit voltage of 0.95 V and good device stability.; National Basic Research Program of China [2013CB834702]; National Natural Science Foundation of China [91433114]; Research Grant Council of Hong Kong [14303314, T23-407/13-N]; SCI(E); 中国科学引文数据库(CSCD); ARTICLE; 2; 257-263; 60
