Color-Tunable Ultralong Organic Phosphorescence: Commercially Available Triphenylmethylamine for UV-Light Response and Anticounterfeiting.
Gao W, Liu Z, Dai X, Sun W, Gong Q, Li J, Ge Y. Gao W, et al. Chem Asian J. 2023 Aug 15;18(16):e202300450. doi: 10.1002/asia.202300450. Epub 2023 Jul 7. Chem Asian J. 2023. PMID: 37387329
Due to the unclear mechanism and lack of effective design for color-tunable ultralong organic phosphorescence (UOP) in a single-component molecule, the development of new types of single-component UOP materials with color-tunable property remains challenging. Herein, commercially …

A new polymorph of triphenylmethylamine: the effect of hydrogen bonding.
Khrustalev VN, Borisova IV, Zemlyansky NN, Antipin MY. Khrustalev VN, et al. Acta Crystallogr C. 2009 Feb;65(Pt 2):o31-4. doi: 10.1107/S0108270108042911. Epub 2009 Jan 10. Acta Crystallogr C. 2009. PMID: 19190382
It was found that the polarity of the solvent does not affect the capability of triphenylmethylamine to crystallize in the different polymorphic modifications. ...It would seem that either the kinetic factors or the effects of the other products of the reaction facilitatin …

Excimer emission from polycyclic arenes bearing triphenylmethyl group: Solid-state fluorescence, mechanofluorochromism, aggregation-induced emission and cell imaging application.
Zheng Y, Chen P, Niu Z, Wang E. Zheng Y, et al. Spectrochim Acta A Mol Biomol Spectrosc. 2024 May 5;312:124035. doi: 10.1016/j.saa.2024.124035. Epub 2024 Feb 12. Spectrochim Acta A Mol Biomol Spectrosc. 2024. PMID: 38422929
Herein, a series of excimer emissive luminogens were obtained by conjugating different polycyclic aromatic aldehydes (anthraldehyde, pyrenealdehyde and perylenealdehyde) with triphenylmethylamine. In crystalline states, all the molecules were arranged in the form of pi-sta …

Spirobifluorene-Based Porous Organic Salts: Their Porous Network Diversification and Construction of Chiral Helical Luminescent Structures.
Okubo K, Oka K, Tsuchiya K, Tomimoto A, Tohnai N. Okubo K, et al. Angew Chem Int Ed Engl. 2024 Apr 8;63(15):e202400475. doi: 10.1002/anie.202400475. Epub 2024 Feb 16. Angew Chem Int Ed Engl. 2024. PMID: 38279903
To diversify the network topology of POSs and extend its functions, this study focused on using 4,4',4'',4'''-(9,9'-spirobi[fluorene]-2,2',7,7'-tetrayl)tetrabenzenesulfonic acid (spiroBPS), which is a tetrasulfonic acid comprising a square planar skeleton. The POS consisting of s …

Synthesis and evaluation of thymine-derived carboxamides against mitochondrial thymidine kinase (TK-2) and related enzymes.
Priego EM, Balzarini J, Karlsson A, Camarasa MJ, Pérez-Pérez MJ. Priego EM, et al. Bioorg Med Chem. 2004 Oct 1;12(19):5079-90. doi: 10.1016/j.bmc.2004.07.036. Bioorg Med Chem. 2004. PMID: 15351391
The couplings were performed in good yields (from 60% to 90%), with the exception of those that incorporate the highly crowded triphenylmethylamine (e). From the new synthesized compounds, the N-trityl-6-(thymin-1-yl)hexanamide (IIIe) was the most active TK-2 inhibitor (IC …
