Optically switchable transistor via energy-level phototuning in a bicomponent organic semiconductor.
Organic semiconductors are suitable candidates for printable, flexible and large-area electronics. Alongside attaining an improved device performance, to confer a multifunctional nature to the employed materials is key for organic-based logic applications. Here we report on the engineering of an electronic structure in a semiconducting film by blending two molecular components, a photochromic d...
Porphyrinic compounds comprise a diverse group of materials which have in common the presence of one or more cyclic tetrapyrroles known as porphyrins in their molecular structures. The resulting aromaticity gives rise to the semiconducting properties that make these compounds of interest for a broad range of applications, including artificial photosynthesis, catalysis, molecular electronics, se...
Atom transfer radical polymerization (ATRP) was used as a versatile route to well-defined poly(diethylhexyl-p-phenylenevinylene-b-styrene) (PPV-b-PS) semiconducting block copolymers. For this purpose, original conjugated macroinitiators were synthesized from DEH-PPV and further used for the copolymerization reaction. The microphase-separated morphologies obtained with the semiconducting PPV-bPS...
Lamellar nanocomposites based on semiconducting polymers incorporated into layered inorganic matrices are prepared by the co-assembly of organic and inorganic precursors. Semiconducting polymer-incorporated silica is prepared by introducing the semiconducting polymers into a tetrahydrofuran (THF)/water homogeneous sol solution containing silica precursor species and a surface-active agent. Semi...
Abstract Optoelectronics is an active area of research and, for few decades, development different semiconducting materials with a wide emission window has attracted researchers. Organic light emitting diodes (OLEDs) are primarily utilized in displays and sources that greatly contribute towards the conservation energy do not need backlight displays. Development device efficiency, lifetime stabi...
قطعات لایه نازک فتالوسیانین مس با الکترودهای آلمینیومی به وسیله تبخیر حرارتی پی در پی در خلا با فشار تقریبی 00001/0 میلی بار بر روی زیر لایه های شیشه ای تمیز شده، آماده شدند . اندازه گیری های ac در محدوده ی فرکانس های 100 تا 100000 هرتز و در فاصله دمایی 300 تا 430 درجه کلوین بررسی شده است. مقدار ظرفیت و عامل اتلاف با افزایش فرکانس کاهش می یابند و ظرفیت با افزایش دما افزایش پیدا می کند. نتایج ن...
background: toluene is a volatile organic compound, one of 189 hazardous air pollutants (hap s ) and the most important pollutant found in most industries and indoor environments; owing to its adverse health, toluene must be treated before being released into the environment. methods : in this research study, a continuous-flow system (including an air compressor, silica gel filters and activate...
Single-crystal semiconductors have been at the forefront of scientific interest for more than 70 years, serving as the backbone of electronic devices. Inorganic single crystals are typically grown from a melt using time-consuming and energy-intensive processes. Organic semiconductor single crystals, however, can be grown using solution-based methods at room temperature in air, opening up the po...
