合成了5，11-和5，12-双（二异丙基硅基）萘并苯（2a和2b），并研究了它们的电子性质。在紫外-可见光谱中，2a和2b的最低能量吸收带比并四苯的更强。化合物2a和2b显示出强烈的黄绿色荧光，荧光量子产率几乎是萘并苯的两倍。
5,11- and 5,12-Bis(diisopropylsilyl)naplithacenes (2a and 2b) were synthesized, and their electronic properties were Studied. In UV-visible spectra, the lowest energy absorption bands of 2a and 2b are more intense than that of naphthacene. Compounds 2a and 2b show intense yellow-green fluorescence, and the fluorescence quantum yields are almost two times higher than that of naphthacene.
