The unexpected interaction between thiazole orange (TO) and calix[4]arene sulfonate is reported herein. H-Aggregates of TO switching on their fluorescence in solution are observed. Surprisingly, fluorescence enhancement is not linked to host-guest inclusion, but rather to calix[4]arene sulfonate serving as a template for several TO molecules.

Cation-exchange resins are used in the management of hyperkalemia, particularly in patients with end-stage renal disease. These resins were associated with gastrointestinal tract lesions, especially sodium polystyrene sulfonate (Kayexalate) mixed with sorbitol. We present a case of colonic necrosis after the administration of calcium polystyrene sulfonate (Kalimate) not suspended in sorbitol.

In the crystal structure of the title compound, C(16)H(12)O(3)S, the dihedral angle between the naphthalene ring system and the phenyl ring is 65.21 (3)°. The mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds, forming a chain along the a axis. The chains are connected through weak C-H⋯π inter-actions.

BACKGROUND Pyrimethamine [2,4-diamino-5-(p-chlorophenyl)-6-ethylpyrimidine] is an antifolate drug used in anti-malarial chemotherapy. Pyrimidine and aminopyrimidine derivatives are biologically important compounds owing to their natural occurrence as components of nucleic acids. RESULTS In the crystal structures of two organic salts, namely pyrimethaminium benzenesulfonate monohydrate 1 and 2...

Interfacial engineering for the regulation of charge carrier dynamics in solar cells is a critical factor fabrication high-efficiency devices. Based on successful preparation highly dispersible graphdiyne oxide (GDYO) with large number functional groups, we fabricated organic employing GDYO-modified poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate) (PEDOT:PSS) as hole transport materials...

Advances in organic materials manufacturing have enabled the creation of electronic devices using solution-processing techniques by employing soluble with high conductivity grade. In this exploratory study, use micro-contact for poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) polymer ink deposition as high-quality structured electrodes field-effect transistors (OFETs) top-con...
