Lattice‐Matched Epitaxial Growth of Organic Heterostructures for Integrated Optoelectronic Application

Abstract

Development of nanowire photonics requires integration of different nanowire components into highly ordered functional heterostructures. Herein, we report a sequential self‐assembly of binary molecular components into branched nanowire heterostructures (BNHs) via lattice‐matched epitaxial growth, in which the microribbon backbone of 2,5‐Bis(5‐tert‐butyl‐2‐benzoxazolyl)thiophene (BBOT) functions as blue‐emitting microlaser source to pump the nanowire branches of BODIPY. By constructing Au electrodes on both branch sides and measuring the photocurrent in them, we successfully realize the integration of an organic laser and a power meter in a single device. This work provides a new insight into the integration of 1D organic nanostructures into BNHs for realizing organic multifunctional photonic devices.

Ein organischer Laser: Verzweigte Nanodrahtheterostrukturen wurden durch gitterangepasstes epitaktisches Wachstum hergestellt. Ein BBOT‐Mikrodraht (2,5‐Bis(5‐tert‐butyl‐2‐benzoxazolyl)thiophen) fungiert als blau emittierende Mikrolaserquelle zum Pumpen der BODIPY‐Nanodrahtverzweigungen.

    Polymers with Helical Blocks

    Polymers, the basis of all plastics, usually do not have an ordered structure, in contrast to biopolymers such as proteins. A team of researchers has now developed a polymer that can be differentiated into folded (ordered) and unfolded (disordered) domains using UV irradiation. The team’s w ... more

    Methane from Carbon Dioxide

    Recycling carbon dioxide (CO2), especially through conversion to methane (CH4), is compelling while anthropogenic CO2 emissions are still rising. A useful process for this transformation is photothermal methanation, in which CO2 and hydrogen are catalytically converted into CH4 and water u ... more

    Liquid Fuels from Carbon Dioxide

    A new electrocatalyst called a-CuTi@Cu converts carbon dioxide (CO2 ) into liquid fuels. As reported by a team of Chinese researchers in the journal Angewandte Chemie, active copper centered on an amorphous copper/titanium alloy produces ethanol, acetone, and n-butanol with high efficiency. ... more
