Photo-induced electron transfer between carbon dots and menadione in non-ionic micelles: A triplet states study with magnetic field

RK Behera, L Mishra, A Panigrahi, P Dubey… - Chemical Physics …, 2023 - Elsevier
Compared to homogeneous surroundings, the kinetics of ultrafast photo-induced processes
gets perturbed in self-assemblies. Herein, we attempt to unveil the photophysical alterations
in highly luminescent carbon dots (CDs) with menadione (MQ-Vitamin K3), in homogeneous
aqueous medium and nonionic Brij-35 self-assemblies. With a series of steady-state and
time-resolved studies, we report photoinduced electron transfer between the CDs and MQ
for Brij-35. Host-guest-like encapsulation in micelles can severely deter the diffusion …
