A continuous production of polyhydrocarbon (PHC) by electrochemical polymerization of chlorinated hydrocarbons is presented. Monomer loading and product transfer were controlled by changing flow direction in a home-built continuous flow...

We describe a structural analysis method for hyperbranched polyhydrocarbon (PHC) produced by electrochemical polymerization. NMR techniques including 1H-NMR, quantitative 13C-NMR, DEPT 13C-NMR, and 1H-13C HSQC 2D NMR along with elemental...

We studied the intercalation chemistry of graphitic carbon nitride (gCN), combining theory and experimental methods. A series of new alkali-ethylenediamine-gCN products were prepared using a one-pot topochemical synthesis method. Spectroscopic and thermal analyses showed t h a t s i n g l e -s t a g e i n t e r c a l a t e d g C N c o m p o u n d s o f L i -( e t h y l e n e d i a m i n e ) 0 . 2 ( C 3 N 4 . 5 H 1 . 5 ) 1 . 0 a n d N a -(ethylenediamine) 0.3 (C 3 N 4.5 H 1.5 ) 0.9 with ordered layer structures were formed. X-ray diffractograms indicated a large gallery expansion of 0.349 and ∼0.342 nm for Li-and Na-intercalated gCN. In the case of K-en-gCN, a nanocomposite was formed that underwent spontaneous in situ exfoliation followed by disordered restacking to form thin flakes. Molecular dynamics studies showed that ethylenediamine molecules were distributed at the center of the interlayer spaces, predominantly adopting a trans conformation. Different types of gallery sites were present for the intercalation of guest alkali metals, leading to a high degree of topochemical intercalation with organic entities under lower temperatures than previously reported in thermal intercalation experiments. Our new synthesis route enables facile intercalation to tune interlayer spacing in gCN.
