Utilizing this method to prepare dye suspensions could potentially reduce the energy consumption associated with the production of liquid disperse dyes.

While certain efficient small molecules have been documented in the literature, they often incorporate bulky alkyl chains and/or aromatic rings to enhance the photothermal effect. Hence, this study presents a novel and straightforward method for synthesizing a photothermal small molecule, designated as <strong>PA2</strong>, utilizing a donor-acceptor framework. In this framework, diphenylamine is employed as the donor moiety, while 1,3-Bis(dicyanomethylidene)indan is utilized as the acceptor moiety. <strong>PA2</strong> demonstrated high PCE in both monomer and but also in aggregate state. In which, the excitation energy is efficiently released as heat via non-radiative decay through the conical intersection (CI) as confirmed by a computationally optimized minimum energy crossing point (MECP) and a combination of further theoretical studies and experimental control groups (<strong>PA3</strong> and <strong>PA4</strong>). Notably, the resulting molecular architecture exhibits remarkable efficacy in inhibiting tumor growth after a 10-day photothermal therapy period. Furthermore, <em>in vivo</em> experiments in a mouse tumor model demonstrate the favorable biocompatibility of these photothermal small molecules, signifying their suitability for safe application in biomedical contexts.

Similar to related structures, the uncoordinated compounds do not exhibit fluorescence in either solution or the solid state. The intramolecular hydrogen bonds in their molecular structure promote an excited-state intramolecular proton transfer (ESIPT) process, leading to an excited keto tautomer that deactivates through non-radiative decay. Protonation and boron complexation can successfully inhibit the ESIPT process, resulting in fluorescence recovery, which can be finely tuned by modifying the substituents on the aryl group. Advanced techniques, including X-ray diffraction, density functional theory (DFT), and time-dependent DFT (TD-DFT), provide critical insights into the electronic structure and emission properties.
