Chemometrical analysis of ortho effect of benzoic acids with electron-acceptor substituents in accordance with AISE.
The series of 2- and 4-substituted benzoic acids with electron-akceptor substituents have been syntetised. Dissociation constants have been measured and substituent effects have been analysed using chemometric method....

HOMO and LUMO energy levels of N,N- dinitrophenyl-substituted polar diketopyrrolopyrroles (DPP)
. The LUMO levels (3.65-3.69 eV) are almost independent of the polar substituents. DFT calculations reveal LUMO exclusively on 2,4-dinitro-phenyl substituents. The energy of LUMO is close to the optimal range for electr...
