Abstract: Porphyrin-based GUMBOS and nanoGUMBOS were synthesized for potential application as improved photosensitizing materials. In this study, porphyrin dyes [meso-tetra(4-carboxyphenyl)porphine (TCPP) and zinc(II) meso-tetra(4-carboxyphenyl)porphine (Zn-TCPP)] were selected as anions, and trihexyltetradecylphosphonium (P66614) was employed as a cation. The resulting [P66614] 4 [TCPP] and [P66614] 4 [Zn-TCPP] GUMBOS (group of uniform materials based on organic salts) provided high photostability and excellent thermal… Show more

“…1A) by ionassociation. [79][80][81][82][83][84][85] For this, we mixed TPE-DPA-Py iodide (2 μM) with a 10-fold molar excess of the corresponding counterions in water. Dynamic light scattering (DLS) measurements showed that TPE-DPA-Py iodide in the presence of counterions forms relatively small particles ranging from ca.…”

“…The observed 50 nm red shift for AIEgen with bulky counterions is probably related to much larger dimeter of TPE-F5 and TPE-F12, 1.16 and 1.60 nm, respectively, in comparison to PF6 and ClO4, 0.33 and 0.35 nm, respectively, which can induce larger dye-dye distance in case of bulky counterions. It should be noted that the dye salts with these counterions are amorphous materials, sometimes called as frozen ionic liquids, 80,83,84 which do not allow X-ray crystallography. Therefore, better understanding of the counterion effect will require a dedicated theoretical study.…”

“…Investigations into a group of uniform materials based on organic salts (GUMBOS), which are composed of frozen ionic liquids and related organic salts with melting points ranging from 25 to 250°C, provide potential applications in sensing, labeling, and optoelectronics due to exceptional tunability of their chemical and optical properties. 1 Colloidal nanoparticles prepared from GUMBOS are termed nanoGUMBOS and have been recently studied as candidates for photovoltaics, 2,3 biomedical imaging, 4 and molecular sensing. [5][6][7] Previously, we have reported on ultrafast excited-state dynamics of colloidal crystalline ruthenium bipyridine-bis(pentafluoroethylsulfonyl) imide ([Ru(bipy) 3 ]- [BETI] 2 ) that show spectral shifts and sizedependent relaxation dynamics.…”

“…1a, and they were synthesised following protocols previously reported. [23][24][25][26][27] An imidazole based ligand for axial coordination was selected, because imidazole derivatives bind more strongly than pyridine derivatives to Zn-porphyrins. [28][29][30] In order to select the optimum components to be used in the subsequent preparation of Na-ZnTCPPImGNP exploiting axial coordination, the complexation in solution was evaluated between the model porphyrin ZnTPP (in toluene) or Na-ZnTCPP (in water) and different alkylimidazoles: methyl imidazole (Im-C1), 1-(11mercaptoundecyl)imidazole (Im-C11-SH) and octadecylimidazole (Im-C18) (Fig.…”
