Embodiment 1

[0018] The preparation of embodiment 1, TTF-TCNQ nanorod

[0019] In a 100mL single-necked flask, add TTF (9.4mg) into 20mL of n-hexane, ultrasonically disperse until completely dissolved, and then stir. TCNQ (13.6 mg) was ultrasonically dissolved completely in 20 mL of acetonitrile, and after being transferred to the capillary dropping funnel, the acetonitrile solution of TCNQ was added to the TTF solution through the capillary dropping funnel, and the rate of addition was controlled to be 1 μL / s (microliter / s seconds), after the completion of the reaction, a black solid was obtained at the bottom of the single-necked flask, and the solid was centrifuged, washed twice with n-hexane, and dried at room temperature for 2 hours to obtain a black powder, with a yield of 95%.

Abstract

The present invention discloses process of preparing nanometer TTF-TCNQ material. The process includes the following steps: 1. dispersing and dissolving TTF in normal hexane to form normal hexane solution of TTF; 2. dispersing and dissolving TCNQ in acetonitrile to obtain acetonitrile solution of TCNQ; and 3. adding the acetonitrile solution of TCNQ into normal hexane solution of TTF while stirring to obtain nanometer TTF-TCNQ material. The present invention synthesizes 1D nanometer TTF-TCNQ material as organic conductor, realizes the controllable growth of nanometer particle, and can obtain nanometer material with different controllable forms and structures. The preparation process is simple and high in yield, and the prepared nanometer material may be applied widely in sensor, field emission plane display, field effect device, non-linear optical material, piezoelectric material and other fields.

Description

technical field [0001] The invention relates to a method for preparing nanometer materials, in particular to a method for preparing TTF-TCNQ nanometer materials. Background technique [0002] TTF-TCNQ (tetrathiofulvalene-tetracyanoquinoquinone) is the world's first charge-transfer complex with metal conductance (Wudl F, Smith G M, Hufnagel E J, J Chem Commun, 1970, 1453), its successful synthesis brought the study of organic conductors into a new stage of development, and made the study of organic conductors one of the fastest-growing scientific research fields in the past three decades. This is mainly due to the fact that organic conductors have many different properties from metal conductors (such as anisotropy) and some potential advantages (such as variable structure, lighter weight, and cheaper price, etc.). One of the most likely application prospects is to provide a substitute for silicon and germanium from organic semiconductors, thereby bringing a new revolution to...
