“…The effects of electric field on the size and shape of deposited particles were investigated by using the EPD of 1a as an example according to the literature, and the results are displayed with the SEM images in Figure a–c. When the deposition potential was changed from 2 to 3 V, a growing number of vesicles were deposited and polymerized on the surface of indiumtinoxide (ITO), and the ITO surface became rougher.…”

“…Usually, blue‐phase PDAs are nonfluorescent, while their red‐phase counterparts are fluorescent, which makes PDAs more applicable to fluorescence‐based sensor systems, even biosensor . According to the literature, the fluorescent properties of PDAs 2a – 2c at different temperatures have been further investigated (Figure S13, Supporting Information).…”

Serial novel chiral polydiacetylenes (PDAs) are efficiently prepared at room temperature by the controllable electrophoretic deposition of diacetylenes with tunable structure as designed from easily available starting materials. The colorimetrically reversible properties of PDAs in the range between 25 and 85 °C are influenced by the different amino acid moiety in the PDAs as anticipated. The PDA containing aromatic ring is much better for the colorimetrically reversible properties, while irreversible thermochromism is displayed for the PDA with the structure of the longer methylene units in the main chain of amino acid moiety.

a Silicone/fluorine-functionalized polyacrylates were synthesized and subsequently used to prepare corrosionresistant transparent coatings via electrophoretic deposition. The coated tin plate with the functionalized polyacrylate had a gloss value higher than 95.0 GU and resisted rust after immersion in a 5 wt% NaCl solution for 10 days. In addition, these coatings remained adhered strongly to the tin plates even after they were bent. It is hoped that this work will provide useful experimental data and assist researchers with the design of applicable coatings with desirable properties.

Since the pioneering discovery by Wagner, 1 polydiacetylenes (PDAs) have been extensively investigated as potential materials for sensor systems as well as active components of optical and electrical devices.2,3 Undoubtedly, the most appealing and promising features of PDAs are their stress induced colorimetric and fluorogenic transitions that have been harvested as a response to thermal, chemical, mechanical and biological recognition events. have been described. In this work, we demonstrate a simple and straightforward method to pattern PDA supramolecules using LangmuirBlodgett (LB) deposition and micro-contact printing (μ-CP). The general procedure consists of the following steps. First, a surface-patterned polydimethylsiloxane (PDMS) mold is replicated from a photoresist-patterned silicon substrate. 17Secondly, LB films of the PDA supramolecules are deposited on the surface of the patterned PDMS.18 Lastly, the PDA LB films are selectively transferred onto silicon substrates using the μ-CP technique. The combination of LB deposition and μ-CP can conveniently fabricate micronsized patterns of PDA supramolecules. Therefore, we believe the patterned PDA supramolecules will find great utility in sensor and optical applications. Figure 1 shows a surface pressure-molecular area (π-A) isotherm of a diacetylene monolayer derived from 10,12-pentacosadiynoic acid (PCDA) on the water subphase. The surface pressure starts rising at an area of 100 Å 2 and gradually increases upon compression until the onset of a plateau-like region at about 35 mN/m. Upon further compression, the surface pressure rises to nearly 48 mN/m. The LB multilayers were prepared by accumulation of up-strokes and down-strokes at a pressure of 25 mN/m on PDMS substrates. The quality of the deposited monolayer on a substrate can be evaluated by the transfer ratio. For an ideal transfer, the transfer ratio is equal to 1. Transfer ratios for diacetylene supramolecule deposition on PDMS substrates are close to 1 during up-strokes but these are close to zero during down-strokes (data not shown here). This result indicates that diacetylene supramolecules transfer onto the PDMS surface only for up-strokes, which is due to the hydrophobic PDMS surface.Figure 2(a) and 2(c) shows optical images of diacetylene supramolecule patterns on Si substrates fabricated by transferring a diacetylene supramolecule LB layers using the
