“…In addition, they all degrade similarly upon the onset of sublimation. Common for these dyes Note that quinizarin [17] is the same as 4-Ring-OH if the left ring is removed, i.e., the four leftmost carbon atoms.…”

“…That being said, our previous work on the deeply orange dye quinizarin in MLD was based on this approach. [ 17 ] The next step was to redesign dye molecules to increase their volatility by adding functionality to the core structure to enable chemical reactivity and to reduce intermolecular forces. This approach is the focus of the current work.…”

Molecular layer deposition (MLD) is an incredibly powerful and flexible tool for designing completely new materials with novel and unique properties. The low temperature layer‐by‐layer approach and the use of highly reactive reactants allows one to combine vastly different organic and inorganic species and construct nanostructures with subnanometer precision. If not limited by the volatility of the reactants involved, the possibilities will be endless. This is most notable for the organic building blocks where an overall low volatility severely limits the toolbox of large molecules with interesting optical and electrical properties such as red‐ox activity and optical conversion. In this work, different strategies for molecular design of large molecules are investigated that allow vaporization while still having the necessary reactivity for MLD growth. Using these strategies, film growth with perylene and porphyrin derivatives, both molecules well known for their functional and optical properties are successfully achieved. With this knowledge, there is an opening to include much larger and more complex organic molecules into the world of vapor phase chemistry.

organic ligands act as bridges between the metal centers to form infinite 1D, 2D, or 3D structures. These materials are often referred to as coordination polymer (CP) [1] or metal-organic framework (MOF) [2] materials; the latter term is used when the metal-organic material is crystalline and highly porous. [3] The research field of CP-and MOF-type materials has grown tremendously over the last two decades. The structural and chemical diversity of these materials has served as a continuous source of scientific excitement; the same diversity has also triggered huge technological interest as these materials possess enormous potential to be tailored for a wide variety of applications ranging from gas capture, storage, and separation to sensing, catalysis, optics, electronics, and energy storage. [4][5][6][7] Most of the targeted application breakthroughs of metal-organics require that these materials can be produced as highquality thin films and coatings, which can be integrated with the other components in the actual device configuration. The possibility to deposit such thin films in an industry-feasible manner on the substrate types needed, would be a major step forward in the field. [8] Traditionally, solvent-based processes such as liquid-phase epitaxy, Langmuir-Blodgett, layer-by-layer, and electrochemical deposition techniques have been used for metal-organic thin films. [9][10][11] These are, however, incompatible with the requirements set by the possible integration of the materials in microelectronics. This is due to corrosion and contamination risks, and the problems in patterning and precise deposition on high-aspect-ratio features. Hence, it is vital to develop solventfree thin-film deposition routes for the metal-organic material family. In the optimal case, these deposition methods should allow conformal coatings on large-area and high-aspect-ratio substrates.The currently strongly emerging ALD/MLD technique is uniquely suited to address the challenge in a scientifically elegant yet industrially feasible way. This technique is derived from the two parent gas-phase thin-film techniques: ALD for inorganic materials (mostly binary metal oxides, sulfides, and nitrides), [12][13][14] and its counterpart MLD for purely organic thin films (e.g., polyimides and polyamides). [15] In both cases, the attractive film growth characteristics are derived from the unique way of separating the different precursor gas pulses. Currently, ALD is the standard thin-film technology in many Atomic layer deposition (ALD) for high-quality conformal inorganic thin films is one of the cornerstones of modern microelectronics, while molecular layer deposition (MLD) is its less-exploited counterpart for purely organic thin films. Currently, the hybrid of these two techniques, i.e., ALD/MLD, is strongly emerging as a state-of-the-art gas-phase route for designer's metal-organic thin films, e.g., for the next-generation energy technologies. The ALD/MLD literature comprises nearly 300 original journal papers covering most of the alkali...
