Two multichromophoric FRET macrocycles M1 [1+1] and M2 [2+2] with red emission ( ∼ 721 nm) composed of perylenediimide (PDI) as the energy donor and aza-BODIPY (ABDP) as the energy acceptor were synthesized by click reaction in a metal-free fashion. M1 and M2 exhibited distinct reversible ratiometric temperature responsive emission with temperature sensitivities of 0.09-0.14% °C and owing to the redox active chromophores, they showed solution phase redox responsive reversible colour changes.
两个多色荧光共振能量转移(FRET)大环 M1 [1+1] 和 M2 [2+2] 具有红色发射(∼721nm),由作为能量供体的苝二酰亚胺(PDI)和作为能量受体的氮杂 BODIPY(ABDP)组成,通过点击反应在无金属条件下合成。M1 和 M2 表现出明显的可逆比率型温度响应发射,温度灵敏度为 0.09-0.14% °C,并且由于氧化还原活性发色团,它们表现出溶液相氧化还原响应的可逆颜色变化。
