Tailored for Binding: Alanine‐Modified Poly(1‐Naphthylamine) Targets Serum Albumins

Polymer Engineering &Science, EarlyView.
Alanine modified poly(1‐naphthylamine). ABSTRACT This study presents a new approach for modifying the structural and functional properties of poly(1‐naphthylamine) (PNA) by incorporating the amino acid alanine (Ala) in different molar proportions (80/20, 50/50, and 20/80 for PNA/Ala) through an ultrasound‐assisted polymerization process.

Hypervalent iodine(III)-induced oxidative [4+2] annulation of o-phenylenediamines and electron-deficient alkynes: direct synthesis of quinoxalines from alkyne substrates under metal-free conditions.

Chemical Communications, 2013
Hypervalent iodine(III)-induced oxidative [4+2] annulation of o-phenylenediamines and electron-deficient alkynes under metal-free conditions has been developed. The reaction allows for direct access to quinoxalines bearing two electron-withdrawing groups

Machine learning‐driven advances in carbon‐based quantum dots: Opportunities accompanied by challenges

Responsive Materials, EarlyView.
Machine learning provides a unifying framework to connect structure, fluorescence properties, and applications of carbon‐based quantum dots. This review highlights how data‐driven strategies enable fluorescence regulation, reveal underlying mechanisms, and accelerate the rational design of functional carbon dots.

NITROSUBSTITUTED 1,2-PHENYLENEDIAMINES

Proceedings of The 14th International Electronic Conference on Synthetic Organic Chemistry, 2010
The 1H, 13C and 15N NMR spectra, both in solution and in the solid state, of five 1,2-phenylenediamines have been recorded. Assignment of all the signals has been achieved and chemical shifts and coupling constants determined. When necessary homo- and heteronuclear 2D NMR experiments have been performed.
