Photoresponsive Host–Guest Functional Systems

Crystal structure of bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane)-9,9-dioctylfluorene, C41H64B2O4

“…Small fluorescent molecules have been developed due to the easy structural modification and tunable photophysical properties in various functional design, such as molecular machine, logic operation, OLEDs [6][7][8][9]. Fluorene is a typical blue fluorescent molecule and used as building block in functional polymers.…”

A M2L2 Redox-Active Metalla-Macrocycle Based on Electron-Rich 9-(1,3-Dithiol-2-ylidene)Fluorene

“…These self-assembled architectures are usually characterized by an internal cavity that can be exploited in guest encapsulation leading to various applications such as chemistry in confined space [8,9] or drug delivery [10][11][12]. Beyond the synthetic challenge in preparing such objects, there is a strong interest in providing them with functionality, as encountered with recently described stimuli responsive rings and cages structures [13][14][15][16]. In this context, the preparation of redox-active metalla-rings/cages which allow a redox control over their overall charge appears relevant [17,18] and we described recently the first examples of electron-rich redox-active coordination cages capable of modulating their encapsulation properties through a redox stimulus [19,20].…”

Photoswitchable Supramolecular Systems Based on Carboxyl Derivatives of Thiacalix[4]arene and Their Complexes with Zn(II) and Tb(III) Ions

“…Одним из наиболее удобных и доступных способов управления супрамолекулярными структурами является свет, с помощью которого можно эффективно переклю-чать их физические и химические свойства, контроли-ровать процессы связывания/освобождения субстратов различной природы. [4,5] Хорошо известно, что каликсарены являются удоб-ной макроциклической матрицей для дизайна моле-кул-хозяев, [6][7][8][9] новых амфифильных соединений, [10][11][12] Схема 1.…”
