A covalently linked porphyrin–fullerene C60 dyad 5 was synthesized by 1,3-dipolar cycloaddition using 5-(4-formylphenyl)-10,15,20-tris[3-(N-ethylcarbazoyl)]porphyrin, N-methylglycine and fullerene C60. Methylation of 5 was ...

Herein, we demonstrate the efficiency of NbCl5 to promote a multicomponent reaction (MCR) for the synthesis of a library of phthalonitrile-quinoline dyads, which are very useful and new functionalized building blocks for ...

Abstract Background Dyad learning has been shown to be an effective tool for teaching procedural skills, but little is known about how dyad learning may impact the stress, ...

This study aims to raise which practices of buyer-supplier dyad are related to the financial performance of the manufacturing industry in Brazil. Based of 174 Brazilian companies and a total of 312 respondents, the analysis ...

In animal behaviour studies, association indices estimate the proportion of time two individuals (i.e. a dyad) spend in association. In terms of dyads, all association indices can be interpreted as estimators of the ...

The effects of an intentional infant sign language program on mother-infant interactions were studied. Design was quasi-experimental, longitudinal, descriptive and comparative. The sample was composed of 14 mother-infant ...

A hole- and electron-conducting polymer has been prepared by electropolymerization of aporphyrin–fullerene monomer. The porphyrin units are linked by aminophenyl groups to form a linear chain in which the porphyrin is an ...
