ROYAL SOCIETY OPEN SCIENCE 2018; 5:172399. [PMID: 30109060 PMCID: PMC6083691 DOI: 10.1098/rsos.172399] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/26/2018] [Accepted: 06/04/2018] [Indexed: 06/08/2023]
Abstract
Carminic acid, a natural hydrophilic dye extensively used in the food and cosmetic industries, is converted in hydrophobic dyes by acetylation or pivaloylation. These derivatives are successfully used as biocolourants for rubber objects. In this paper, spectroscopic properties of the carminic acid derivatives in dimethyl sulfoxide and in polybutylacrylate are studied by means of photoluminescence and time-resolved photoluminescence decays, revealing a hypsochromic effect due to the presence of bulky substituents as the acetyl or pivaloyl groups. Molecular mechanics and density functional theory calculations confirm the disruption of planarity between the sugar ring and the anthraquinoid system determined by the esterification.

Abstract
A series of triblock copolymers based on poly(vinyl pyridine)–PEG–poly(vinyl pyridine) (PVP–PEG–PVP) with different PEG-to-PVP ratios (1 : 200, 1 : 250, and 1 : 500) were prepared using the RAFT polymerization.
