Macrocyclic luminophores under confinement in a polymeric matrix – induction of large-Stokes shift by inter-unit proton transfer

“…2a). 14 The derivatives possessing OH groups, e.g. 1a , demonstrated large Stokes shifts due to ESIPT.…”

“…1a–c , 2a–c , and 3a–4c were synthesized according to literature procedures. 14 The synthetic procedures for 1d–e , 2d–e are described in ESI †…”

A brand-new type of excited-state proton transfer (ESIPT) molecule based on sulfoxide/sulfenic acid tautomerism

“…1,[26][27][28][29][30][31][32][33][34] With multiple donors and multiple acceptors in a compound, multiple ESIPT processes can occur, resulting in a process known as multiple-ESIPT. [35][36][37][38] Once the compound returns to the ground state via radiative or non-radiative transitions, the hydrogen atom undergoes a reverse transfer, from N 2 to N 1 , O to N, or O 2 to O 1 to return to its initial state. Due to the ESIPT principle, the compound exhibits dual fluorescence emission within a single molecule.…”

Remote control of anion binding by CH-based receptors

“…Compounds 4, 5, 7, and 8 were synthesized previously for a different purpose. 18 The synthesis of 6 and 9 is reported in ESI. For the initial assessment of properties, DFT calculations 19 were performed for 3a-9a (analogues of 3-9 devoid of lower rim alkyl substituents, which have negligible influence on relevant parameters, Fig.…”
