  2. 1. Hyperconjugation in Group 14 Organic Compounds : Design and Property Investigations

    Author : Aleksandra Denisova; Henrik Ottosson; Thomas Müller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 1; 4-disilacyclohexa-2; 5-diene; aromaticity; computational chemistry; conjugation; cross-hyperconjugation; hyperconjugation; group 14 elements; organosilicon chemistry; silole;

    Abstract : Nowadays π-conjugated molecules are widely used as materials for devices in organic and molecular electronics. This is due to the ability of such molecules to conduct electricity. However, π-conjugation leads to molecular rigidness and associated lower solubility, which limits possible applications. READ MORE
