利用相容剂调控聚噻吩/富勒烯共混薄膜形貌
摘要:
选择含有噻吩环的富勒烯衍生物([6,6]-噻吩基-C61-丁酸甲酯(TCBM-Cn,n代表在噻吩环5位的烷基链碳原子数))作为聚3-己基噻吩(P3HT)和[6,6]-苯基-C61-丁酸甲酯(PCBM)共混体系的相容剂,讨论了结晶能力不同的TCBM-Cn分子对共混体系相容性和P3HT结晶行为的影响。当使用强结晶性的相容剂TCBM-C0时,虽然不能完全抑制PCBM的聚集,但由于分子中噻吩环结构的存在,少量的相容剂即可提高P3HT的结晶度。而对于弱结晶性的相容剂TCBM-C6,虽然可以完全抑制PCBM的聚集,但是只有当其含量超过PCBM时,最终才能达到促进P3HT结晶的目的。

Morphological Manipulation of P3HT/PCBM Blend Thin Films by Using Compatibilizers
Abstract:
[6,6]-Thienyl-C61-butyric acid ester derivatives with different alkyl chains at the 5-position of thiophene ring(TCBM-Cn,n represents the number of carbon atom in the alkyl chain) are introduced as compatibilizers in poly(3-hexyl thiophene)/[6,6]-phenyl-C61-butyric acid methyl ester(P3HT/PCBM) blend films.The effect of different crystalline ability of TCBM-Cn on the thermal stability and the crystallization of P3HT in blend films is discussed.Although it is difficult to completely prevent the aggregation of fullerene,a small amount of good crystalline compatibilizer can enhance the crystallization of P3HT.To the contrary,poor crystalline compatibilizer can completely prevent the aggregation of fullerene,but more compatibilizers are required to improve the crystallization of P3HT.
