Photophysics, Dynamics, and Energy Transfer in Rigid Mimics of GFP-based Systems

Abstract: Engineering of novel systems capable of efficient energy capture and transfer in a predesigned pathway could potentially boost applications varying from organic photovoltaics to catalytic platforms and have implications for energy sustainability and green chemistry. While light-harvesting properties of different materials have been studied for decades, recently, there has been great progress in the understanding and modeling of short- and long-range energy transfer processes through utilization of metal-organi… Show more

“… 6 , 7 The isolated chromophore is virtually non-fluorescent in solution 8 and in vacuo , 9 but can become fluorescent when incorporated in rigid scaffolds such as metal–organic frameworks or other non-native protein environments. 10 13 The lack of fluorescence from the free chromophores is widely accepted to be due to ultrafast isomerisation around the C 2 –C 3 –C 4 bridge ( Fig. 1 ) followed by efficient internal conversion taking excited state population back to the electronic ground state.…”

“…Furthermore, the isolated chromophore is virtually non-fluorescent at biological temperatures in solution [69] and in vacuo [70], but it fluoresces strongly in solution when cooled to 77 K [69] and it has been found to have a sufficiently long excited state lifetime in the gas phase when cooled to 100 K that fluorescence may occur in vacuo at low temperatures [71]. The isolated chromophore can also become fluorescent when incorporated in rigid scaffolds, such as metal-organic frameworks or other non-native protein environments [72][73][74][75]. The lack of fluorescence from the free chromophore at biological temperatures is attributed to ultrafast isomerisation around the central C-C-C bridge linking the phenolate and imidazolinone moieties ( Fig.…”

“…[9] Most chromophores are non-fluorescent in solution due to the mobility of their benzylidene fragment which can dissipate their excited-state energy. [10] However, they becomeh ighly emissive when the flexible substituenti s fixed by an externali nfluence [11] or by an internal lock. [12] Previously they weres uccessfully used as fluorogens for various proteins, [13] nucleic acids, [14] and whole cell organelles.…”
