摘要
设计合成了一种新的有机磷光基元(菲咔唑)，并掺杂进不同的高分子材料制备成薄膜.研究结果表明掺杂聚乙烯醇(PVA)薄膜有着磷光发射强度大、磷光寿命长(
τ
= 2.12 s)、磷光量子产率高(
Φ
p
=7.95%)等优点. 离子自由基通过形成电荷分离态参与了超长磷光的发射过程. 相较于掺杂聚甲基丙烯酸甲酯(PMMA)薄膜，掺杂PVA薄膜呈现更明显的长余晖，这是由于PVA薄膜提供了更加刚性的环境，磷光基元与PVA分子间相互作用力极大增强，从而促进了电荷分离态的形成，减少了分子运动引起的非辐射耗散及薄膜中氧气对三线态激子的淬灭.此外，掺杂PVA薄膜具有水刺激响应性质，在水的刺激下可以发生磷光性能的改变，因此可应用于信息加密、湿度检测等场景.
Abstract
Benzocarbazole and its derivatives have excellent ultralong organic room temperature phosphorescence (RTP) properties. Polymer films can help benzocarbazole molecules achieve better phosphorescence performance. In this paper
a new organic phosphorescence unit named 9
H
-dibenzo[a
c]carbazole (CzNPh) is designed and synthesized
and thin films are prepared by using different polymer materials. Compared with the doped poly(methyl methacrylate) (PMMA) films
the doped poly(vinyl alcohol) (PVA) films of CzNPh have higher phosphorescence intensity
longer phosphorescence lifetime (
τ
= 2.12 s)
higher phosphorescence quantum yield (
Φ
p
=7.95%). Radical ions participate in formation of charge separation states and are involved in the emitting process of ultralong phosphorescence. Rigid environment in PVA films and enhanced interactions between CzNPh and PVA facilitate formation of charge separation states and reduce non-radiative transition caused by molecular motion and the quenching of triplet excitons by oxygen. In addition
CzNPh@PVA films can also realize the stimulation response to water because water can damage the interactions between CzNPh and PVA
so CzNPh@PVA films can be applied in information encryption
humidity detection
etc
.
