Abstract
Unexpected discovery that molecules of organic dyes when they form regular structures can change dramatically their light absorption and fluorescence properties were attracting the minds of researchers for more than eight decades. The progress in investigation of this unique phenomenon described in terms of H- and J-aggregation has led to many practical applications. Here the author expresses his personal view on the dramatic story of switching this research area from empirical knowledge to that standing on strong background of molecular exciton theory. The author was a witness of some of these events and acquainted with several great personalities involved. The major trends of future developments are highlighted.
期刊介绍：
The Chemical Record (TCR) is a "highlights" journal publishing timely and critical overviews of new developments at the cutting edge of chemistry of interest to a wide audience of chemists (2013 journal impact factor: 5.577). The scope of published reviews includes all areas related to physical chemistry, analytical chemistry, inorganic chemistry, organic chemistry, polymer chemistry, materials chemistry, bioorganic chemistry, biochemistry, biotechnology and medicinal chemistry as well as interdisciplinary fields.
TCR provides carefully selected highlight papers by leading researchers that introduce the author''s own experimental and theoretical results in a framework designed to establish perspectives with earlier and contemporary work and provide a critical review of the present state of the subject. The articles are intended to present concise evaluations of current trends in chemistry research to help chemists gain useful insights into fields outside their specialization and provide experts with summaries of recent key developments.
