Organic molecules of DIDB can inherently assemble into fluorescent green-emissive microwires with a low photoluminescence quantum efficiency (PLQY) of 1.0%. Impressively, by doping DIDB into the nonluminous 4-iodobenzonitrile crystal matrix with a molar ratio of 1 : 100, phosphorescent yellow-emissive microwires with a much higher PLQY of 50.5% are obtained.
DIDB 的有机分子可以自发组装成发荧光绿光的微米线，其光致发光量子效率（PLQY）仅为 1.0%。令人印象深刻的是，通过将 DIDB 以摩尔比 1:100 掺杂到无发光的 4-碘苯甲腈晶体基质中，得到了磷光黄色发射的微米线，其 PLQY 高达 50.5%。
