The rational design of supramolecular polymers in water is imperative for their widespread use, but the design principles for these systems are not well understood. Herein, we employ a multi-scale (spatial and temporal) approach to differentiate two analogous water-soluble supramolecular

Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) has been widely utilized for the structural characterization of various synthetic polymers. However, polymer sample molecules can occasionally decompose even in the MALDI process depending on the measurement conditions. In this work, the fragmentation

A novel electron rich, tetrathiafulvalene fused zinc porphyrin, (TTF)4PZn, has been newly synthesized and characterized using spectral and electrochemical methods. In spite of the presence of eight t-butyl groups, (TTF)4PZn exhibited appreciable aggregation in solution. Scanning electron microscopic (SEM) imaging
