Alkoxy substituted D-π-A dimethyl-4-pyrone derivatives: Aggregation induced emission enhancement, mechanochromic and solvatochromic properties

Three series of D-π-A 2,6-dimethyl-4-pyrone-cored derivatives were designed and synthesized. Evaluation by spectroscopic methods indicated that all the compounds exhibited aggregation-induced emission enhancement (AIEE) effect and solvatochromism. The experimental results revealed that the restriction of intramolecular rotation is the key element for showcasing the AIEE phenomenon. Moreover, all of the compounds presented red-shifted mechanochromic behavior, the extent of the red-shift was mainly dependent on the position and length of alkoxyl group. The PXRD and DSC profiles demonstrated a transformation from crystalline to amorphous state upon grinding. The D-A strategy introduced in this work could facilitate the development and application of ingenious mechanochromic materials.

Alkoxy-position effects on piezofluorochromism and aggregation-induced emission of 9,10-bis(alkoxystyryl)anthracenes

Changing the linking positions of alkoxy chains can significantly alter the aggregation-induced emission and piezofluorochromic activities of 9,10-bis(alkoxystyryl)anthracenes.

Reactions in microemulsion media: Schiff bases with targeting/anchoring module as kinetic sensors to map the polarity pocket of a microemulsion droplet

The hydrolysis of some tailor-made Schiff bases having flexible spacers between aldimine groups and alkoxy groups at ortho (o) or para (p) position in the benzene ring has been investigated in microemulsion media. The kinetic data of acid-catalyzed hydrolysis in anionic (sodium lauryl sulphate: NaLS) and cationic (cetyltrimethyl ammoniumbromide: CTAB) microemulsion media have been explained considering the localization of the Schiff bases at various probable pockets of the microemulsion droplet. The results are in conformity to the solubilization studies of the reported Schiff bases in microemulsions (Dash et al., Spectrochim Acta 1996, 52A, 349). The change in reactivity due to change in the spacer length and position of the alkoxy group in the Schiff bases has been rationalized on the basis of localization sites of the reaction center at different polarity pockets of the reaction media.

Hydrolysis of schiff bases in (CTAB-CHCl3-H2O) reversed micelles: Role of spacers

The schiff bases of the type (p-C16H33O-C6H4CH = N)2(CH2)m (1, m=0, 2, 3, 4 and 6) and the ortho isomer (2, m=0, 2, 4, 6) have been synthesized and the hydrolysis of these compounds these compounds have been studied in CTAB-CHCl3-H2O reversed micellar system under acidic condition.Significant variation of the reaction rate has been observed due to variation in the number of methylene groups in the spacer and due to the change in the position of the cetyloxy group.Difference in the rate of disappearance of schiff base and appearance of the product is ascribed to a mechanism involving a carbinolamine intermediate.

Synthesis and Spectral Analysis of Some Schiff Bases Containing Long Alkyl Chains

Schiff bases containing hydrophobic alkyl chains have been synthesized and the IR, 1H NMR, 13C NMR, and mass spectral data of some of the compounds have been reported.
