摘要
本文合成了1,3-取代方酸衍生物:1,3-双[4-二甲胺苯基]-2,4二羟基环丁二烯氢氧双内盐(DMCS),1,3-双[4-双十六烷胺苯基]-2,4二羟基环丁二烯氢氧双内盐(DHCS)。研究了DMCS和DHCS在不同溶剂中的光物理行为,估算了DMCS、DHCS的基态与激发态之间偶极矩差值。在CTAB胶束中,除DMCS单体分子外,DMCS形成了二聚体。在二氧六环-水体系中,研究了DHCS的簇集行为,并测定了DHCS的临界簇集组成(C_ψ)及临界簇集浓度(C_A)
The compounds 1,3-bis(4-dimethyaminopheny1)-2,4-dihydroxy-dihydroxide cy-clobutenediylium bis(inner salt)[DMCS]and 1,3-bis(4-dihexadecylaminopheny1)-2,4-di-hydroxy-dihydroxide cyclobutenediylium bis(inner salt)[DHCS]were synthesized.The photophysical behaviors of DMCS and DHCS in different solvents were studied and their differences of dipole moment between ground state and excited state were calculated.Dimer ofDMCS in CTAB and aggregate of DHCS in dioxane-water were investigated and criticalaggegation composition(C_Ψ)and critical aggregation concentration(C_A)of DHCS weremeasured.
