主　　题：BODIPY Nonfullerene acceptor Small molecule donor Photovoltaic cell Solution processed 

摘      要：Five boron-difluorodipyrromethene（BODIPY） dimers have been designed and synthesized successfully via acid-catalysed condensation and Pd-catalysed cross-coupling *** structural modification,including verifying the structures of the π-bridges,altering the positions the bridges link（meso-or β-positions）,and regulating the molecular planarity,can modulate the photophysical properties and the aggregation behaviors of the five dimers ***-processed organic solar cells were fabricated to evaluate the photovoltaic properties of these molecules further either as acceptors or *** using as nonfullerene acceptor and blended with the polymer donor of PTB7,an opencircuit voltaic（V_（oc）） of 1.12 and 1.08 V was achieved from the thiophene and benzodithiophene bridged BODIPY dimers,*** V_（oc） is among the top values achieved from the non-fullerene organic solar cells so far.
