We have achieved the first series of -based building blocks, viz., s ( = 1-4), and unraveled a rational design of their π-extension. Sequentially increasing numbers () of the exocyclic π-linkers showed (a) a systematic bathochromic shift in both absorption and emission spectra, (b) selective stabilization of the lowest-unoccupied molecular orbital (LUMO), and (c) unselective changes in the S/S states. To our surprise, the LUMO level of (-3.72 eV) was found to be comparable to that of PCBM.
我们已经制备出了第一系列基于[具体物质]的结构单元，即[物质名称]（ = 1 - 4），并阐明了其π-扩展的合理设计。依次增加环外π-连接基团的数量（）显示出：（a）吸收光谱和发射光谱均出现系统性的红移；（b）最低未占据分子轨道（LUMO）的选择性稳定；（c）S/S态的非选择性变化。令我们惊讶的是，发现[物质名称]的LUMO能级（-3.72 eV）与PCBM的相当。
