Special Issue Information

Dear Colleagues,

Liquid crystals (LCs) are a fascinating class of soft matter that exhibit features of fluidity and long-range order. LCs have the intrinsic property of self-organization and give rise to unique physical and optical properties. This has inspired researchers to design and fabricate stimuli-responsive materials and devices for applications in a wide variety of areas.

Considering the outstanding importance of the development of new state-of-the-art liquid crystals, this Special Issue welcomes the submission of original research manuscripts, reviews embracing aspects of LC science and technology, and theoretical and experimental investigations ranging from mesogen design and synthesis to applications.

Potential topics include, but are not restricted to:

  • Design, synthesis and characterization of rod-like (calamitic), bent-core and discotic LCs
  • Functional liquid-crystalline polymers and supramolecular LCs
  • LC display science and technologies, optical alignment, switching materials, optical information processing and devices
  • Liquid crystalline properties beyond the biological applications
  • Liquid-crystalline sensitizers for singlet oxygen formation and solar cells applications
  • Investigation of triplet–triplet annihilation (TTA) in liquid crystals
  • Liquid-crystalline thermally activated delayed fluorescence (TADF) emitters
  • Environmental issues related to disposal of materials used in organic devices

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Blue phases (BPs) have a frustrated structure stabilized by chirality-dependent defects. They are classified into three categories: blue phase I (BPI), blue phase II (BPII), and blue phase III (BPIII). Among them, BPIII has recently attracted much attention due to its elusive amorphous structure and high-contrast electro-optical response. However, its structure has remained unelucidated, and the molecular design for stabilizing BPIII is still unclear. We present the following findings in this review. (1) BPIII is a spaghetti-like tangled arrangement of double-twist cylinders with characteristic dynamics. (2) Molecular biaxiality and flexibility contribute to stabilize BPIII. (3) BPIII exhibits submillisecond response, high contrast, and wide-viewing angle at room temperature without surface treatment or an optical compensation film. It was free from both hysteresis and residual transmittance. The electro-optical effects are explained in relation to the revealed structure of BPIII. Finally, we discuss the memory effect of a polymer network derived from the defects of BPIII. Full article
