A novel series of benzo-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acids (benzo-Tic), designed by extending the aromatic system of Tic (Tic=1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid) in three different orientation, has been synthesized.

Structural control of solubilizing side groups in fullerene-based electron acceptors is critically important to optimize their performance in bulk heterojunction (BHJ)-type polymer solar cell (PSC) devices. The structural changes of fullerene derivatives

A modular synthetic platform for the construction of flexible glycoluril-derived molecular tweezers was developed. The binding properties of four exemplary supramolecular hosts obtained via this approach towards 16 organic amines were investigated by means of 1H NMR titration. In this work, we compare the Ka values obtained this way with those of three structurally related molecular tweezers and provide a computational approach towards an explanation of the observed behavior of those novel hosts. The results showcase that certain structural modifications lead to very potent and selective binders of natural polyamines, with observed binding of spermine below 10 nM. This journal is
Cationic Tags for Attomole Level Detection of Analytes by Mass Spectrometry

Paragraph 0080, (2018/02/28)
The invention provides methods of detecting an analyte by multi-stage mass spectrometry with improved S/N ratio. An analyte is labeled with a positively-charged mass tag to form a precursor ion that leads by anchimeric assistance to a greatly enhanced, analyte-characteristic first product ion that can, in turn, lead to a greatly enhanced, analyte-characteristic second product ion in a mass spectrometer. Either a three stage mass spectrometer (true MS3) or a two-stage mass spectrometer (MS2) operated in a pseudo MS3 mode can be used. The precursor ion is split via an anchimeric-assisted reaction to form a first product ion, which in turn can be fragmented to form the second product ion. The methods offer extreme ultrasensitivity, at the low amol level. The invention also provides anchimeric mass tags for use in the methods. A wide variety of previously undetectable analytes of biological or environmental origin can be detected and quantified.
